I have been out of practice on the routing problems and i know im missing something important but i cant seem to find out what it is

i have a primary network 192.168.1.0/24 the main router ip is 192.168.1.1, it has all the servers and all the pcs are wired, and i also have a wifi network 192.168.10.0 /24 were the wireless router is 192.168.10.1 but its wan access is 192.168.1.10, its gateway is 192.168.1.1

i can ping and connect from inside the wifi network to anyone, either 192.168.10.1 or 192.168.1.0, BUT i cant ping anyone from anyone in 192.168.1.0 to 192.168.10.0

i have the dhcp active on both routers and in both networks i have full internet access
